The trial of Atlanta teachers accused of falsifying test scores to meet ambitious progress targets is now underway. Some teachers facing up to 35 years in prison, the Los Angeles Times reports.

"Atlanta Public Schools was once hailed as one of the highest-performing urban districts in the nation," the LA Times notes. "Test scores climbed so rapidly that its chief, Beverly Hall, was named National Superintendent of the Year in 2009 by the American Association of School Administrators."

The results, it turned out, were too good to be true.

The real problem, argues Maureen Downey at the Atlanta Journal Constitution, is that schools are approaching teaching wrong. By focusing on standardized tests with bubble, pencils and Scantrons, schools invite cheating.

"This scandal is a cautionary tale," Tim Callahan, a spokesman for the Professional Association of Georgia Educators, told the LA Times. "If we continue to overemphasize test scores, there will be more bad apples."

Usually, it's kids, but it can be teachers, too, when promotion and retention hinge on producing measurable results, Downey argued.

"The culture of accountability that Superintendent Beverly Hall imposed on the system, however, pressured school personnel to engage in blatantly unethical practices to create the appearance of learning," Downey writes. "This appearance was necessary because her brutal testing regime used standardized test scores as a proxy for learning, and forced teachers who might have taught in more open-ended ways to conform to rote teaching to these tests, lest the teacher assessment system identify them as incompetent."

Cheating itself is a blurry concept, notes Anya Kamenetz at NPR. Teachers can cheat all kinds of ways short of erasing answers and penciling in corrections.

Kamenetz cites research showing a range of gradations that run from teaching to the test to focusing only on those on the bubble, ignoring those who are either certain or unlikely to pass.

One researcher, Kamenetz says, "documented teachers diverting resources and time to the group of students who looked like they were closest to passing the test. These kids, who might make the minimum passing score if given intensive help, were described as being 'on the bubble.'"

"Correspondingly," Kamenetz adds, "the teachers gave less attention to a lower-scoring group that they were encouraged to label as 'hopeless cases,' as well as the kids who would pass the test no matter what. The upshot was that a relatively small number of students received a disproportionately high amount of the teaching and resources available."

"The APS cheating scandal, then, is more than an ethical disgrace," Downey concludes at the AJC. "It is a tragedy of teaching and learning, as those teachers who challenge kids to inquire into complex questions must knowingly make a mockery of their life’s work in order to meet a false standard of effectiveness. For that, we should all feel ashamed."

Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
